What is the relationship between the rate at which a drug is cleared from the body and the urgency in wanting another dose?

The relationship depends on the drug being used

The slower the drug is cleared, the greater the urgency

The faster the drug is cleared, the greater the urgency (correct)

Study Notes

Factors Affecting Drug Addiction

Urges to use a drug can be increased by various factors, including the rate of onset, duration of action, and rate of clearance from the body.

Relationship Between Clearance Rate and Urgency

A faster rate of clearance from the body can lead to a stronger urge for another dose, as the individual may experience withdrawal symptoms or a decrease in the drug's effects.

Duration of Action and Addictiveness

Drugs with a longer duration of action are generally considered less addictive, as they provide a more sustained effect and may reduce the frequency of use.

Features Determining Addictiveness

According to the introduction to psychopharmacology, the rate of onset, duration of action, and rate of clearance can determine the addictiveness of a drug.

Faster Rate of Onset

A faster rate of onset is associated with increased addictiveness, as the rapid increase in dopamine levels can lead to greater reinforcement and repeated use.
